When disassembled for transport, a prototype-size deathtrap (4′ 6″ struts) occupies 0.8 cubic feet (4.5’xflexible) and should weigh around 60lbs; a grown-up-size deathtrap (5′ struts) occupies 1.5 cubic feet and weighs around 100lbs; a kid-size deathtrap (3′ 4″ struts) occupies 0.6 cubic feet and weight around 50 lbs.
Fully assembled, the prototype-size deathtrap stands at around 7′ 6″ when resting on a side, and opposite corners are about 8′ apart; a grown-up-size deathtrap stands at around 8′ 6″ on its side and 9′ between opposite corners; a kid-size deathtrap stands at around 5′ 6″ on its side, and 6′ between opposite corners. (These values are partly calculated, partly guessed, and mostly rounded; actual measurements may be a while coming.)
The vertices on all sizes of deathtrap are made from a 3/8×4″ galvanized steel eye bolt, with a nylon lock nut threaded all the way down it, a flat washer, (the struts), another flat washer, a lock washer, and an ordinary nut. The nuts can be turned with a 9/16″ wrench, and the threads are 3/8″NC (i.e. 14tpi–in case they become damaged and need to be re-cut). Acorn/cap nuts are often placed on the end of the bolt in order to keep gunk out of the threads, or to keep the end of the bolt from scratching or otherwise damaging its environment. Half tennis balls can also be added over the corners to provide additional protection.
